A closer look

What the research shows

Human research on a combination

The multi-ingredient regimen improved melasma measures over 12 weeks relative to baseline, with pigment comparisons to hydroquinone on normal protected skin.

What this does not tell us

40 females enrolled, 38 completed. Co-active biomimetic oligopeptide 68, sunscreen and other lightening ingredients prevent isolated diacetyl-boldine attribution. Facial clinical efficacy was a before/after regimen outcome, not a facial vehicle comparison.
